Just check out that mustache. David Niven once reigned supreme as Hollywood's suavest English sophisticate, and there was something about that impeccably groomed swath of facial hair that encapsulated his charms: equal parts worldly adventurer (Around the World in Eighty Days) and magnetic mischief-maker (The Pink Panther). Not to mention his conversational prowess, a skill that's been favorably compared to his acting (which is saying something when you've got an Academy Award at home). Niven's most memorable Oscar moment came not in 1959—when his name was actually pulled from the envelope—but as a host in 1974. Looking sharp as ever in a shawl-collar tudo, he was interrupted by an exhibitionist streaking across the stage. The 65-year-old Niven responded by calling the man's "shortcomings" into question—and proved that he still had the power to win over a room with the slightest flicker of a smile.—RAFI KOHAN

Invest in a good pair of grooming scissors or clippers. A mustache—and especially one as thin as Niven's—is a bold style statement. Keep yours reined in.
